I am considering adding members to a DAG from two different sites to achieve site resilience. Is this possible?
Background: We have 6 sites two of which are house mailbox servers, hub servers, and client access servers. The choices are as follows:
1) One DAG with 6 servers spanning over two sites.
2) Two DAGs with 3 servers in each site.
Option 1 is preferred as long as DAGs can cross site boundaries. Is Option 1 possible for site resilience?
